An 80-year-old Granbury woman died Wednesday night, several hours after sustaining what had appeared to be non-life-threatening injuries in a two-vehicle accident.

The accident occurred at about 7:45 p.m. in the 3800 block of Highway 377 East, near H-E-B.

Granbury Police Deputy Chief Alan Hines said late Thursday that it is not yet known whether Virginia Blade Martin died from injuries sustained in the accident, or whether there was some other cause. An autopsy will be performed, he said.
